You can pic up a complete short block for that price if all you want is a stock rebuild. Pull your heads and intakes, clean and inspect and swap them and all accessories to new motor. Should be able to do it in a weekend with hand tools

I would maybe do .030 over but idk it's just a cruzer so I'd probably stay stock.. What's it cost to take mine in and have it rebuilt.?

If you have a stock block. No reason to go 030 over. That is just to clean up the piston walls etc.

IMO once past .30 over will not be as reliable as a DD

exactly. you will weaken the cylider walls and thin them out with risk of running hot all the time.

Re: New block or rebuild?

Stop and consider exactly what you want to do with the car AND if you ever think you may want to use nitrous or forced induction.For most purposes a stock shortblock will be just fine, but if you desire to use nitrous or forced induction, then an aftermarket block is strongly recommended.


When buying a pre-assembled shortblock you want to be sure to do so from a trusted vendor. I can't tell you how many times in the past I have found defects, non matching rods or pistons, out of spec bores, rings installed wrong, rods installed wrong and many other sloppy and improper rebuild issues. (They count on most people NOT checking for these shoddy building practices.)


Do not buy any shortblock that has been bored over .030". Cast iron blocks are poured into sand molds and sometimes the molds slip. Ford set the .030 overbore max to ensure that the cylinder walls do not become to thin during rebuilds. If the block mold has slipped, an overbore to .040" - .060" will dangerously weaken the cylinder walls and lead to overheating or breakage.


IMO, you would probably be better off if you rebuild the engine you have.

A lot of times you can get by just fine, but if you really start putting the pressure to it, it is likely to fail or overheat at some point.


If you check for core shift and have the block sonic tested to ensure the cylinder walls are thick enough you can go as much as .060" overbore. I have done that back in the 80's and the engine held up ok, but every time it was ran hard it would overheat. You could actually open the throttle and watch the heat gauge climb at the same time. The blocks were poured using a thinwall casting technique (done to save weight) that makes them weak to begin with and over boring past the recommended .030" is just not a good idea.

I don't believe in nitrous.. And I Dought I will ever use forced.. Do you know the average cost to take it in and have someone rebuild it? I can pull it and everything but I can't tear to deep into her..

Usually you can get it done under 1000$ but every area/shop varies so much, no one on here could give you a good estimate. I would just get on the phone and see. Let us know what they say.

That's very true. What I don't like is having to constantly mess with filling the bottles. Other than that you can't beat the cost for a power adder.

You might have chosen the wrong car then.
Luxury & Fox Body, just do not fit together.

I'm using luxury vaugely.. I mean more like ugh beauty? I love the power these things can put out but let's face it I don't have a track within 100 miles of me.. So I want something I can take out on the weekends ect. Beautiful paint witha perfect interior. And at the end of the day still be able to light up the tires..

I'm considering rebuilding my 302 block, nothing is wrong with it. Runs smoothly, no knocks, no nothing. I just want to ensure that the entire engine is clean, and sludge free.
